It turns out the earlier diagnosis of Jackson being questionable was too optimistic. The team's official Twitter account is reporting that the star running back will be out for the rest of the game against the Jets.

Given where the Bills are at right now in this game, that is probably the most sensible move. The Jets are all over them, and while they need to keep pressing to come back in that game, they have to focus on making sure he can return as soon as possible.

Jason La Canfora of CBS Sports is reporting that Jackson may not be able to return today thanks to the diagnosis.
Initial diagnosis for Fred Jackson is sprained LCL. Likely done for the day. Will get further tests this week.— Jason La Canfora (@JasonLaCanfora) Sept. 9, 2012
The Bills are losing by 20 to the Jets as of this writing, so they may not want to risk bringing him back out in a game that is so one-sided.
---------END OF UPDATE------------
Jackson was in the midst of a breakout season last year before breaking a bone in his leg that forced him onto injured reserve. He was the biggest reason the Bills started out so well, and without him they were a different team.
We will keep you updated on the situation as more information becomes available, but given the way Jackson walked off the field, he didn't look too happy.
